Abstract: In this project I used different food wrappings to determine which wrapping will keep refrigerated apple slices the freshest. I cut 15 apple slices, and I had four different food wrappings. I wrapped three apple slices in each wrapping. I made sure each apple slice was separate from the other. I left three apple slices unwrapped to see how they reacted to not being covered. I predicted that the aluminum foil would protect and keep the apple slices the freshest. Introduction…

Antibiotics are substances that can destroy or prevent the growth of the bacteria and cure infections. In 1928, Alexander Fleming who was a Scottish biologist, pharmacologist, and botanist found the first antibiotic, penicillin, in the world. It was a significant discovery in the medical field. During the World War II, the penicillin had saved many lives. According to PBS, “400 million units of pure penicillin were manufactured” and “650 billion units a month” were produced by the end of 1945…

My idea for a science project is to investigate whether “the five-second rule” is true or not. I decided on this project after my mom took a microbiology class and became obsessive with germs and bacteria. She is constantly telling me to wash my hands and not to eat food that has fallen on the floor. I want to see if my mom’s theory is accurate. During this background research paper, I will cover past similar research experiments, as well as explain the concept of my project and why the results…

"[Industrial meat cows] are three times likelier to harbor a potentially deadly strain of E. coli, and at higher risk of carrying salmonella bacteria and transmitting bovine spongiform encephalopathy, or mad cow disease, as it’s quaintly known." This shows how the industrial meat system hurts animals and consumers. The animals are much more likely to get diseases like E. Coli or salmonella, and consumers become much more prone to these diseases by eating their meat.…

Factory farming is a system of rearing livestock using intensive methods, by which poultry, pigs, or cattle are confined indoors under strictly controlled conditions. Factory farms control the U.S. food production. According to Safe.org.nz “Factory farming began around the nineteen sixties and nineteen seventies with the popularity of fast food” (paragraph 2). It created the ability for companies to buy larger quantities of meat for a lesser amount of money. Factory farming also affects the…

Organic or Conventional Gardening: Which Would You Rather Use? Everyday people are growing more and more concerned of where their food comes from. The push for more organic produce in local grocery stores poses the question if there are marked differences between organic and conventional gardening. With the recent increases in organic farming, people are flocking towards buying organic opposed to buying conventionally grown food. Many wonder if buying organic is really better for the consumer…

Slaughterhouse Abuse Every day, thousands of animals are killed due to improper and inhumane ways of killing for their meat. According to Animal Rights Action, there is such a high demand for meat, workers don’t stop for anything. With improper and poor methods of killing, this can lead to unsafe work areas for the workers, fecal contamination with meat, bacteria and pathogens landing on meat, it makes you second guess where your meat, eggs and milk came from. A lot of times when slaughter…

The objectives of this dissection was to examine the digestive system, the shape and location of the organs. Another objective of the rat dissection was to know the function of the organs in the respiratory system. For our last objective, for the circulatory system we had to identify the blood vessels and state their function. Rat dissections are done in this course because students get to see, touch and examine the organs in the body. Seeing these organs in person instead of just off a piece of…

Chicken and Beast In today food industry billions of companies and industries are producing food everyday for our huge population in the US. But what consumers of food don’t really know is what they’re eating. For example, you may be eating a two-pound rotisserie chicken for you and family, but you may not know what the chicken as been through. An average chicken life span in a chicken farming factory is three months, it’s a fast and sad process. Chicken in these conditions are being pumped…

Ranges in diameter between (0.5- 1) µm and in length between (2-4) µm however, they are either a parasite or live independently they are found in all living things and in all environments. Some bacteria in drinking water can cause disease such as salmonella, total coliform (including fecal coliform and E.coli), Shigella, Legionella, and Campylobacter and “their presence indicates that the water may be contaminated by human or animal wastes”. Some bacteria break down organic matter and play an…
